GLASS-CUTTER.

Application filed. May 3, 1912, Serial 110.684.,886.

To all whom it may concern:

Be it known that I, SIMON LOUIS BRAUN, manufacturer, a subject of the King of the Belgians, and resident of 19 Rue du Regent, Antwerp, Belgium, have invented a certain new and useful Glass-Cutter, of which the following is a specification.

My invention relates to a device for outing glass provided with rowels, the rowels being interchangeable and a stock of them stored in the tool itself. I attain these ob jects by the mechanism illustrated in the accompanying drawing which represents a front view of the glass cutter and in which:

Figure 1 shows the device closed and Fig. 2 the device open. I

' The glass cutter consists of a plate (1) in tempered steel, copper or any other metal that can be used for the purpose. This plate is fitted with another plate (2) which slide-s longitudinally upon plate (1). To this purpose plate (1) is provided with buttons (3) These buttons hold the two plates (1) and (2) together while at the same time allowing plate (2) to slide on plate (1). The rowels are placed in a groove cut in plate (1) and are liberated by the sliding of plate (2). The space opened in the groove is sufliciently large to release one of the rowels. In order to prevent plate (2) from sliding too easily, a stop ((3) holds plate (2) in the closed position and a certain effort is required to slide it. Plate (1) is also prvoided on one side with a handle and on the other with a pivot.

beyond plates (1) and (2) The pivot may be interchangeable and screwed into the plate.

To replace a rowel, it is only necessary to Copies of this patent may be obtained for Specification of Letters Patent.

On this pivot is, placed the rowel which protrudes slightly Patented J an. 25, 1916.

slide out of the groove in plate (1). The I fresh rowel is then placed on the pivot, and to fix it it is only necessary to slide plate (2) toward the right. Now as plate (2) is no longer over the opening to the pivot the rowels are held in place and cannot come out. Plate (2) is provided with a slit so that the rowels stored in the tool are visible. Deep cuts are made in plate (2) so that it does not come into contact with the glass breaking indents.

The instrument may be made in steel or any other suitable metal.

I claim:

In a glass cutting tool the combination with a fiat metal head having a pin or pivot for supporting a rowel or cutter screwed into its extremity, with a sliding plate movable longitudinally between two positions on the said fiat head, the said plate having a hole through which the rowel or cutter supported on the pivot can be removed, when the plate is in the first or nonworking position, said plate covering the pivot and retaining the rowel or cutter in place when in the second or working position.

In witness whereof I have hereunto set my hand in the presence of two witnesses.

SIMON LOUIS BRAUN.
